To all whom t may concern.'

Be it knownthat we, WILLIAM J DANKE@ a citizen of the United States, and a 'resident of Villa Grove, in the county of Douglas 5* and State of Illinois, and CLARENCE E. VAN

PELT, a citizen of the United States, and a n resident of Salem, 'in the county of Marlon. :and'StateA of Illinois, have invented certain l new V and useful Improvements in Graders or l which f the followf `nis alspecication.

'i 'i' I At-the forward end of the truck, the frame 9, is tilted downwardly, as shown' bythe portion 11, in Figi-3. Mounted onv a suitable 85v bearing carried by the tilted portion 11, of the frame 9, near its. end, is 'the lower en'd of ashaft 12, arranged at right angles to the pivoted at the upper steel'and which' is supported Aby afpluralit'y of bolts 22, from the rim 17, and will there-j"` wheel" 1 5, vsprocket "18, "10o showinglffone of the "Shovels .01 SCOOPSO theexcavator wheel;

' to vary the angle at which the scoop will en.

and shaft 12. It Awill be noted that the tilt or angle at which the excavator wheel normally rotates is such that the tip of the outermost of the digging members carried thereby will enter the ground a slight distance.. v

. Interposed betweenthe wheel 15, and the ring 19, are a series of shovels or scoops 20, preferably made of steel and having tapered ends projecting -a suitable distance beyond the periphery ofthering 19. Each of the scoops or shovels 2Q4A has a pair of perforated ears 21, adapted to`slip over one of the bolts 22, and' also is provided with a pair of lugs 23, formed on the back of the shovel, and from which a brace 24 leads to the rim'17 of the wheel 15, as most clearly shown in Fig. 4. The brace 24, is fastened to said rim 17,`bya pin 25, passing through one of a pluralityv of' holes formed in the said brace, and by shifting the pin 25, from one to another of these-holes, the shovel 20, may be moved relative to the ring 19, so as to vary the'distance to whichthe tip of the shovelprolects beyond the edge of the ring 19, and likewise I ter the ground. A

When the machine is driven intoa bank .v or mound to be removed the rotation of the shovel wheels will cause theshovels 20, to plow through th'e earth as they come in contact'therewith, and the excavated dirtwill slide up the innersurface of the shovels 20,

' onto the fiat ring 19, and drop off the inner edge of said ring. Projecting below this. inner. edge ofthe ring 19, is the forward end of a sheet metal conveyer bottom 26, supported 'bythe frame 9 of the machine, and which maybe stifened bysuitable-angle at each end4 and on .Opposite sidesof the'conve'yer-bottom steel formations 27. Mounted 26, are sprocket wheels 28, guiding chains 29, the links of which chains mesh with the teeth [of the sprockets 28. Certain of the.`

links of each chain 29, adjacent the edges of the conveyer bottom 26, are formed with an extension or bracket 30', and'these brackets upon the'two chains extend toward each other and slide upon the upper surface of the .conveyer bottom '26, (as shown in- Fig.

. 2), thereby providing a common support for a scraper bar 31, preferably formedof wood. When the conveyer chains 29, are in motion, these scraper bars 31, 4will move the dirtA dropped upon the conveyer bottom from the inner edge of the ring 19, and carry the same to the rear or inner end of the conveyer.

i When the dirt drops o the end of the confeo veyer 26, it falls upon another conveyer bottom 32, extending transversely of the truck l of the machine and supported tothe frame 9,

' 4 by suitable braces in a horizontal position.

Hingedly connected tothe conveyer' 32, is

y the lower end of a similar operation,

sprocket* 51, is a spur gear 52,

machine.

conveyer bottom 33, which may be positioned at varying angles to the horizontal. Mounted on the under sides of the conveyer bottomsv 32 and 33, near the ends thereof, are suitable sprocket wheels over which pass link chains 34, similar'to the chains 29, of the conveyer 26, and which also carry scraper bars 35, adapted to push the dirt on the said cons veyer bottom 32, laterally of the truck and up the inclined conveyer bottom 33, from the end of. which latter the dirt may drop directly into an adjacent cart or car and be carried away. When thel machine is not in the inclined vportion 33, of the laterally extendingconveyer may be drawn up close to the side of the machine by means of suitable cables. f

For actuating the machine of our invention, we preferably provide a gasolene engine indicated at 36, mounted near the rear of'the truck so as to beeasily `reached by `an loperator positioned close to the steering wheel37, which.' connected through chains' 37, to the ends of the axlev 4, for turning the same relativeto the frame of the machine. The crank shaft of the engine 36, is connected by a link 4chain 38a, with a power shaft 38, one end Yof which carries a sprocket 39, connected by a chain 40,1to a sprocket 41, fixed on one of the forward wheels 1. The shaft 38, loosely carries a sprocket 42, which may be thrown into and out'. of co-action with the shaft by a manually operable clutch 43, and from which a chain 44, drives a secondary shaft 45, connected by bevel'. gears 46, by a sprocket 47, and a chain 48,with the sprocket wheel 18,v of the shaft 12, carrying the exca vator wheel 15. The secondary shaft 45, also carries a sprocket 49, connected by a chain 50, to a sprocket 51, su the frame 9. Mounted onthe s aft-of the which meshes with the teeth f another spur gear 53, fixed to the shaft'of' one of the sprocket wheels 28, of the conveyerchains 29, thereby causing said chains to be moved along the longitudinal conelyer 26, toward the rearof the 'wheels over which the scrape'rschains 29 passt -and through which vgearing these ported by fixed to the shaft of the `sprocket 51, 1s a similar sprocket 54,.which scraper chainsof the :transverse conveyers l are operated.- l Consequently,

motion and the clutch 43,-'is'in its engaging position, theengine w1l1 simultaneously'125 propel the'truck, rotate the ex avator wheel when the engine 36,' isin and actuate both the longitudinal and transverse conveyers. By varying the tilt of the frame 9, of the machine, the shovels or digging members 20, of the excavator wheel may be caused to enter the ground to a -greater or less depth, thereby proportion-l ing the rate of the excavating to the nature of the soil. In case difficulties are encountered, the excavator wheel may be raised to clear the same by manipulating the hand wheels 10 (which may be done without stopping the engine) or the truck may be backed up by throwing out the clutch 43, and reversing the engine through a suitable rel versinggear operated by a lever 57.

When transporting the machine from place to place, the adjusting screws 7,. above truck, a framework movably mountedv .the longitudinal conveyer.

19, not only supports the shovels 20, but.

the axle 3, may be raised to bring the excavator Wheel a suflicient distance from the` ground so that the outermost of the shovels 20, will clear the ground and thereby not interfere withthe travel of the machine.

It will be evident from the above that when thewexcavator wheel is in operation the rotation of the ring 19, will coact with the shovels 20, to cause the freshly excavated dirt to slide the previously excavated ldirt inwardly of the said ring and to drop the same through the interior thereof upon Thus the ring tion, what we claim as new and 4desire to secure by Letters Patent, is-'V 1.
